Measuring color with the EFI ED-100

This section describes the basics of taking measurements with the EFI ED-100. Once you have mastered this technique, see the section “Calibrating with ColorWise Pro Tools using the EFI ED-100”to properly calibrate your copier.

Guidelines for taking color measurements

Keep in mind the following when using the EFI ED-100 to take measurements:

•Ensure the page you are measuring rests on a flat, firm surface.

•Make sure the measurement page does not rest on an intensely colored surface. For more accurate measurement, place blank sheets of the same kind of paper as the measurement page beneath it to block underlying colors from being read by the EFI ED-100.

•Do not touch the patches with your fingers.

•Verify that the aperture is centered over the color patch. Use the aiming guide lines to help you.

•Ensure the EFI ED-100 is pressed against the patch you are measuring.

•Hold the EFI ED-100 at a right angle to measure a row of patches and make sure that it remains perpendicular to the sample row during measurement. This is to ensure that contact is confined to the patch being measured.

TO TAKE MEASUREMENTS USING THE EFI ED-100

NOTE: Software that supports the EFI Densitometer ED-100 (for example, ColorWise Pro Tools Calibrator™) provides the patch pages that you print and measure with the

EFI ED-100.

1.Place the EFI ED-100 over a sample patch so that the sample aperture on the bottom of the EFI ED-100 completely covers the sample patch.

The aiming guidelines on the tip of the EFI ED-100 indicate where the sample aperture is located. The busy indicator light is centered directly above the sample aperture.

NOTE: For more accurate measurement, place a sheet of white paper beneath the sample patch to block underlying colors from being read by the EFI ED-100.

2.Press the green button (Go) to initiate the measurement process.

NOTE: You do not have to hold the button down during the measurement. Typical measurement time is approximately one second.

When the busy indicator light turns off, the measurement is complete and you can move to the next sample to take a new measurement.

Calibrating with ColorWise Pro Tools using the EFI ED-100

Using ColorWise Pro Tools Calibrator and the EFI ED-100, you can quickly measure color patches generated by the copier and download these measurements to the Fiery server.

NOTE: Multiple users can be connected to one Fiery with ColorWise Pro Tools, but only one user at a time can use Calibrator. An error message appears if you try to calibrate when another user is already using ColorWise Pro Tools to calibrate.
